Test Signals
RCD Type Test Signal Description
AC
(sinusoidal)
The waveform is a sinewave starting at zero crossing, polarity
determined by phase selection (0 ° phase starts with low to
high zero crossing, 180 ° phase starts with high to low zero
crossing). The magnitude of the test current is I
P
n x Multiplier
for all tests.
A
(half wave)
The waveform is a half wave rectified sinewave starting at
zero, polarity determined by phase selection (0 ° phase starts
with low to high zero crossing, 180 ° phase starts with high
to low zero crossing). The magnitude of the test current is
2.0 x I
